Abstract: A survey device, for surveying an installation to which a cathodic protection voltage is applied, the cathodic protection voltage exhibiting at least a first transition event (e.g. switch on/off), comprising at least one input adapted to receive an input signal corresponding to electrical activity (e.g. voltage or current detected) arising at the installation from the cathodic protection voltage. A processor is coupled to the inputs and is operable to (i) receive one or more detection signals (e.g. sampled/digitised), at least one detection signal corresponding to or being based upon the input signal; (ii) determine, from the at least one detection signal, the occurrence of the first transition event; and (iii) take a measurement of the electrical activity a predetermined time delay (e.g. configurable by a User on a PDA coupled to the survey device) after the first transition event. The survey device may operate in automatic mode, in which transition events at or near an expected time are monitored, and in the event of discrepancies from the expected, timings such as currently estimated modulation period are adjusted. Also disclosed is a method for surveying an installation to which a cathodic protection voltage is applied.
